Advanced Root Canal & Endodontic Care at Newbury Dental

Root Canal in Brookfield

At Newbury Dental in Brookfield, CT, we understand that severe tooth pain, infection, and the words “root canal” can feel stressful and overwhelming. Our goal is to make advanced endodontic treatment as comfortable, predictable, and conservative as possible—often saving natural teeth that might otherwise be extracted.

For patients who need root canal therapy, endodontic retreatment, microsurgical treatment, or urgent relief from tooth pain and swelling, our office provides in house, specialist level endodontic care in the familiar setting of Newbury Dental. This means you can receive advanced treatment, including 3D CBCT guided diagnosis and endodontic microsurgery (such as apicoectomy), without having to travel to a separate endodontist or oral surgery office.


In House Endodontic Expertise at Newbury Dental

To support our vision of keeping as much care as possible under one roof, Dr. Vanessa Castro collaborates closely with her husband, Haissam “Dr. Sam” Ramadan, DMD, an endodontic specialist with over a decade of focused experience in complex root canal and endodontic cases. He completed his dental and specialty training at an Ivy League institution and has built his reputation on managing difficult teeth that many clinicians consider high risk or even “hopeless.”

Dr. Ramadan’s practice is limited to endodontics, with a special focus on:

  • Complex molar and premolar root canal therapy
  • Endodontic retreatment of previously treated teeth
  • Management of calcified, curved, or otherwise complicated root canal anatomy
  • Endodontic microsurgery, including apicoectomy, when appropriate
  • Emergency endodontic treatment for acute pain, swelling, or trauma

He routinely treats teeth with severe infection, persistent symptoms after a prior root canal, cracked teeth, and roots with challenging anatomy that require meticulous planning and advanced technique. Using modern endodontic microsurgery methods, a Global operating microscope, and J. Morita CBCT 3D imaging, he can see tiny details in root anatomy, detect fractures, and evaluate surrounding bone to design the most predictable and conservative treatment possible.

Over more than ten years of specialty practice, Dr. Ramadan has maintained very high success rates on root canal and endodontic procedures and is particularly sought after for managing retreatments and “last chance” teeth that patients are hoping to save. Patients appreciate his calm demeanor, clear explanations, and step by step approach to relieving pain while preserving their natural teeth whenever possible.


How Our Endodontic Care Is Structured

Dr. Ramadan does not advertise his services to the general public in this area and does not accept outside referrals directly. Instead, he works solely as part of the internal Newbury Dental team, providing advanced endodontic care only for patients under Dr. Castro’s care.

All consultations, treatment planning, and scheduling for root canal therapy, endodontic retreatment, and endodontic microsurgery are handled through Newbury Dental. This structure allows our existing and new patients to benefit from specialist level endodontic care within our practice, while also reassuring local providers that patients referred to Newbury Dental for complex endodontic treatment will return to their established general dentist or specialist for ongoing restorative and preventive care.


A Team Approach to Complex, “Last Chance” Teeth

Many of the endodontic cases we treat at Newbury Dental involve teeth that have already had one or more root canals, teeth with persistent infection around the root tip, or teeth that have been recommended for extraction. When possible, we take a conservative endodontic approach to save these teeth, using CBCT guided diagnosis and true endodontic microsurgery rather than traditional “apico” techniques more commonly used in oral surgery settings.

Dr. Castro and Dr. Ramadan plan cases together, integrating advanced diagnostics (including J. Morita CBCT imaging, Global microscope visualization, and digital scans) with thoughtful restorative planning. This means your root canal, retreatment, or apicoectomy is coordinated with the crown, onlay, implant, or cosmetic work that follows, so your tooth not only feels better but also functions well and looks natural for the long term.

Rather than simply “drilling and filling,” our focus is on diagnosing the true cause of your symptoms, choosing the least invasive solution that still offers a predictable result, and preserving healthy tooth structure whenever we can.


Root Canal Therapy in Brookfield, CT

Root canal therapy is a common procedure used to treat infected or inflamed pulp inside a tooth, relieve pain, and prevent the need for extraction. At Newbury Dental, root canals are performed under high magnification with a Global operating microscope and guided by modern imaging so we can thoroughly clean and seal each canal while protecting as much healthy tooth structure as possible.

You may need root canal therapy if you have:

  • Persistent toothache or pain that wakes you up at night
  • Sensitivity to hot or cold that lingers after the stimulus is removed
  • Swelling, tenderness, or a bump (fistula) on the gums
  • Pain when chewing or biting down
  • Darkening or discoloration of a tooth

Thanks to advanced techniques and effective local anesthesia, most patients report that a root canal feels similar to getting a filling and provides enormous relief once the infection is removed. After treatment, we work with you and your general dentist (if you have one outside our practice) to place the appropriate final restoration, such as a crown or onlay, to protect the tooth long term.


Saving Teeth After a Failed Root Canal

Sometimes a tooth that has already had a root canal can become painful or reinfected months or even years later. In these cases, endodontic retreatment may allow us to save the tooth instead of removing it and placing an implant or bridge.

During retreatment, we carefully re enter the tooth, remove existing root canal filling material, look for missed canals, address any complex anatomy or blockages, and thoroughly disinfect and reseal the system. Advanced tools, CBCT imaging, and the operating microscope are especially critical in these situations, because previously untreated anatomy or tiny fractures are often the key to why the original treatment failed.

Our office sees many retreatment cases referred from other practices specifically because of our experience with challenging anatomy and long standing infections. When retreatment alone is not sufficient, endodontic microsurgery may be recommended as a more targeted solution.


Endodontic Microsurgery & Apicoectomy

Endodontic microsurgery, often called an apicoectomy, is a precise surgical procedure used to treat persistent infection at the tip of the root when standard root canal or retreatment is not enough. Instead of removing the entire tooth, we access the root tip, remove the infected tissue and a small portion of the root, and seal the end of the canal from the root side under high magnification.

At Newbury Dental, apicoectomy is performed as true endodontic microsurgery, using a Global operating microscope, specialized micro instruments, and biocompatible materials to maximize healing and long term success. This approach is different from the more traditional “apico” techniques often used in non endodontic settings and allows for more conservative removal of bone and more precise sealing of the root.

For the right cases, endodontic microsurgery can be a powerful way to save a tooth that would otherwise be extracted and replaced with an implant or bridge.


Emergency Tooth Pain & Swelling

Severe toothache, facial swelling, and dental abscesses should never be ignored. If you are experiencing intense pain, swelling, or think you may need an emergency root canal, contact Newbury Dental right away so we can prioritize your care.

When you call, our team will ask about your symptoms, schedule you for the earliest available visit, and, when indicated, coordinate same day or next day emergency treatment to relieve pain and control infection. In many emergency cases, root canal therapy or microsurgical treatment can stabilize the tooth and help you avoid extraction.


Supporting Local Dentists With Complex Endodontic Cases

Newbury Dental frequently manages complex root canal retreatments, endodontic microsurgery (apicoectomy), and high risk endodontic cases for patients who already have a trusted general dentist or specialist. When a patient is seen here for advanced endodontic care, our philosophy is to support the existing treatment plan and return the patient to their primary dentist for restorative and ongoing care once the endodontic issue is resolved.

Our team communicates clearly with referring providers regarding diagnosis, treatment options, and outcomes, and we remain focused on preserving teeth whenever reasonably possible. This collaborative approach provides your patients access to advanced endodontic resources while protecting and respecting your long term relationship with them.


Schedule a Root Canal or Endodontic Consultation

Root Canal & Endodontics FAQ

Do I need to see a separate endodontist for a root canal?

In most cases, you do not need to travel to a separate endodontic office. At Newbury Dental, we provide endodontist level care in house, including advanced root canal therapy, retreatment, and endodontic microsurgery. You receive the benefits of specialist level technology and training while staying in the same practice where you already feel comfortable.

I had a root canal before and the tooth still hurts. Can it be fixed?

Yes, many painful or failing root canals can be treated with endodontic retreatment instead of extracting the tooth. During retreatment, we carefully remove the old filling material, look for missed or blocked canals, disinfect the root system thoroughly, and seal it again. Our use of 3D CBCT imaging and a surgical operating microscope is especially helpful for diagnosing why a previous root canal did not fully resolve your symptoms.

What is endodontic microsurgery or apicoectomy?

Endodontic microsurgery, often called an apicoectomy, is a precise surgical procedure used when infection or inflammation persists at the tip of the root after root canal treatment or retreatment. Through a small opening in the bone, we remove the infected tissue and a small portion of the root tip and then seal the end of the canal from the root side. Because we use high magnification microscopy and specialized instruments, this approach can often save a tooth that might otherwise need to be removed.

How do I know if I need a root canal instead of a filling?

You might need root canal therapy if you have lingering pain to hot or cold, throbbing toothache, pain when chewing, swelling around a tooth, or a pimple like bump on the gums. A thorough exam and 3D imaging, when appropriate, allow us to determine whether a deep cavity or crack can be treated with a simple filling or crown, or whether the pulp inside the tooth is infected and requires root canal treatment to relieve pain and prevent further damage.

Can you save teeth that other dentists said must be extracted?

In many cases, yes. Our conservative endodontic approach, combined with CBCT guided diagnosis and true microsurgical techniques, allows us to save teeth that were previously recommended for extraction. While not every tooth can or should be saved, we routinely evaluate “last chance” teeth and discuss whether root canal therapy, retreatment, or endodontic microsurgery offers a predictable alternative to extraction and replacement.

What should I do if I have sudden, severe tooth pain or swelling?

Sudden, severe toothache or facial swelling is a dental emergency and should be evaluated as soon as possible. Call Newbury Dental right away so we can assess your symptoms and arrange the earliest appropriate visit, often the same day or next day. Prompt endodontic treatment can relieve pain, control infection, and in many cases help you avoid losing the tooth.
